Weight loss products have great side effects on the body, even if they have weight loss effect, they will rebound. Suggest exercise to lose weight: 1. Aerobic exercise is the most effective and healthy way to lose weight. It is an endurance exercise mainly based on aerobic metabolism. It can improve human metabolism, promote energy consumption, and prevent excess energy from being converted into fat accumulation and decomposing accumulated fat. 2. Aerobic exercise includes jogging, walking (walking and brisk walking), swimming, cycling, running in situ, ball games, mountain climbing, aerobic exercise, practicing yoga and playing Tai Ji Chuan. It is best to complete each exercise continuously at one time, and ensure that it lasts for more than 40 minutes every day, and you can stop in the middle.

Exercise can improve the metabolic rate of human body, but the effect is only two days at most, so the most important thing is to keep exercising. If you can't do it every day, do it at least once every two days. The harm of diet pills must not be ignored. Never believe advertisements and eat diet pills indiscriminately.
